SBI — Transaction done but payment not reached

Address: 302004

I was paying rs 24, 774 for emirates airlines on 8 may 2017. The transaction was done as i received a message but the payment did not reach the airlines. Its been a month now and the money did not come to my account yet. I talked to the airlines they said that they didnt accept the payment so it should come back to my account.
Sbi says that for them the transaction was completed. My money is not back to me yet.
Solve my problem please!
